Congenital Renal Fusion and Ectopia in the Trauma Patient

Figure 2

31-year-old male with crossed unfused renal ectopia. Axial contrast-enhanced CT image (a) shows lacerations (white arrows) through the posterior cortex of the ectopic left kidney, positioned anteriorly and inferiorly in the right abdomen. A perinephric hematoma (red arrow) is noted anteriorly. A coronal CT image (b) shows the uninjured right kidney in a normal location. A sagittal CT image (c) through the right abdomen shows the right kidney (white arrow) in a normal location in the renal fossa and the ectopic kidney (red arrow) in the lower right abdomen. Note the gap between these kidneys in this unfused ectopia.
